Abstract :
We have demonstrated unsurpassed communication performance, only 2 dB from theory, by careful matching of the transmitted waveforms and receiver filtering at all bit-rates using an average power limited (APL) transmitter anti variable duty-cycle waveforms. While we have demonstrated duty cycle enhanced (DCE) multi-rate communications from 51 Mbps through 1.244 Gbps using binary-pulse position modulation (PPM), this approach can easily be extended to higher bit-rates, other modulation formats, and is extremely well suited for M-ary PPM
